( Fig. 32C, D)

Homoriscus macginitei Glassell, 1938: 414   , figs. 1–4.

Naushonia macginitei   . — Goy & Provenzano 1979: 339, figs. 6b,g; 7c, 8c, f, k, l. — Hendrickx 1995b: 159. — Sirota & Martin 2005: 146, fig. 2.

Diagnosis. Rostrum semi-oval, armed anteriorly with small, sharp teeth; upper surface granulate, slightly concave. Carapace lightly pubescent, with 7 sharp longitudinal ridges. Orbit semicircular, outer orbital angle small, blunt. Antennular peduncle longer than rostrum. Scaphocerite with 7–8 sharp teeth on outer margin, shorter than third segment of antennular peduncle. Ischium of third maxilliped armed on inner side with row of spinules, merus with distal tooth, propodus, dactyl subequal in length, longer than carpus. Pereopod 1 subchelate, propodus broad, upper margin carinate, with large fixed tooth, 3–4 smaller teeth on inner margin. Pereopod 2 short, stout; long setae on merus, simple, setose dactyl. Pereopods 3, 4 more slender, longer than second, with few setae; simple, slender dactyls. Abdominal somites without carinae or teeth. Telson rounded, sides with very fine teeth, 3 pairs lateral spines. Exopod of uropod shorter than endopod, both divided by sutures across posterior half. Carapace length to 7.7 mm, total length 19.2 mm.

Color in life. Bright orange, with appendages speckled with white or beige, dorsal surface of abdomen more uniform beige or cream ( Sirota & Martin 2005).

Habitat. Under rocks in pool, among eelgrass ( Zostera sp.   ), sand flats; intertidal zone to 11.2 m.

Range. Newport Bay and La Jolla , California ; Ensenada de San Francisco , Sonora, Gulf of California, Mexico to Wafer Bay, Cocos I., Costa Rica. Type locality La Jolla, California   .

Remarks. This peculiar animal was originally thought to be a sand shrimp ( Caridea   : Crangonidae   ). The similarity in the subchelate first pereopods could be confusing. The sutures of the uropod, the unusual rostrum and the ridges of the carapace are characteristic.
